A type of coffee so diluted by sugar, cream or milk that it no longer tastes like coffee, instead like milk and sugar, and has a beige or light brown color to it. The drink is typically concocted by those who want to appear as if they are drinking coffee but despise the taste.

Jill: Yeah, i hate the taste of her half and half and half.

Get the half in half mug.
In an Irish bar, a drink that's half Guinness and half lager. Not called a "black and tan" since those colors commemorate the british military force used to supress Irish uprisings.
In an English pub I'll order a black and tan, but in an Irish establishment, I'll order a half and half.
